slontis 85407b7754 Fix double free in EVP_PKEY_CTX_dup() 
If the internal operations dupctx() fails then a free is done (e.g. EVP_KEYEXCH_free()). If this is not set to NULL the EVP_PKEY_CTX_free() will do a double free.
This was found by testing kdf_dupctx() in kdf_exch.c (Note this always
fails since the internal KDF's do not have a dup method).
